A former mixed martial arts promoter who was pummeled and robbed by a random attacker in Brooklyn said he was worried about causing a rush hour “blood bath” by fighting back with his fists.

Instead, Patrick Freitas, 48, decided to wrestle his crazed assailant to the ground on a platform at the Utica Ave. A train station, and wound up losing $200 he was planning to spend on a rare night out with friends.

“I just knew if there were punches thrown it was going to turn into a big bloody brawl and I didn’t want to get engaged in a big bloody brawl on Friday, on my day off,” said Freitas. “I just thought, ‘I am going to take him down on the ground and subdue him.’”

Freitas was waiting to transfer to the express train at about 6 p.m., when he heard the man harassing people, screaming “konnichiwa” — Japanese for “good day” — at a group of Asian children, making sexual remarks to a woman, and calling another straphanger a “white ass n—-.”

He came up to me kind of like what are you going to do about it and so I stood to defend myself, and when I stood up he punched me in the face,” Freitas recounted.

The ex-brawler, now a restaurant manager, said he’s promoted MMA fights, but he’s never been in a street scrap.

“I stood up but I didn’t expect him to do something. I figured he was just a big mouth,” he said. “When he punched me, I weighed the consequences. Do I punch him back? What if he falls and gets hurt?”

When the man moved to punch him again, Freitas decided to take him to the floor.

NYPD released a photo of a man they are looking for in connection with a robbery in a Brooklyn subway station.

“I did a double leg take down, I took him off his feet and on his back, he put me in a headlock and so I started punching him and he tried to put his fingers in my eyes and he put his fingers in my mouth, trying to fish hook me,” he said.

A brief video released by police shows the two men wrestling on the ground. Some bystanders pulled Freitas off the man, and the $200 he withdrew for his night on the town fell out of his pocket, he said.

The attacker scooped up the cash and ran off.

“I spent the next four hours with the police on a Friday night,” he said. ”I work a lot, I put a lot of hours in. It was going to be one of those rare nights off I can relax and — well, it’s whatever, it is what it is.”

Cops ask anyone with information about the attacker to call Crime Stoppers at (800) 577-TIPS.

“I hope he gets caught. It seems like he’s the kind of person who seems very comfortable bullying people and treating people in ways they don’t deserve,” Freitas said.
